A homemade urine test promises to help many more women find out if they are at risk for cervical cancer, as an alternative to the Pap test and without having to visit the gynecologist.
Researchers at Queen Mary University in London (UK) asked 600 women to provide samples collected by themselves for analysis with a test defined by charities as a potential "turning point" .
The results were presented at Cancer Conference [1
However, the UK hospitals prefer to do more tests before offering them to their patients.
Although it happens, experts say, cytologies (or pap tests) will continue to be practiced in health centers, but this may be a new and easier alternative for many women.
Researchers expect women to take the test at home and even order the kit over the Internet and then send the samples by mail to be analyzed in the laboratory.
Dr. Belinda Nedjai, one of the responsible for the development of the test, which they called test S5 says it measures the chemical changes detected in urine samples or vaginal fluids to measure the risk of women suffering from cancer.
A high score suggests that there is a growing risk of a pre-cancerous lesion .
In the study, S5 was able to successfully differentiate which women had pre-cancerous lesions diagnosed with the conventional form of detection.
A crucial test
The Pap test aims to detect early signs of cancer known as pre-cancer that can be treated to try to prevent the disease.
All women with cervix between the ages of 25 and 64 are recommended to be tested, but many women avoid doing so many times by shame to show the "smell or appearance" of his private parts, which was revealed by a recent conducted survey in the UK.
Other times, data points out, it is naivety or misinformation about the importance of this test to detect cervical cancer, the most common among 35-year-old women in that country .
It is estimated that one in four British women do not take the test when cited, but the problem extends to other parts of the world.
"Potential" for "revolutionizing"
Nedjai told the BBC that the collection of Prover for the S5 test of women themselves was "fairly accurate", although the test is not as effective as the Pap test.
"But it's coming soon," he added. "With improvements, we will reach that point."
For this, the specialist says, the test should be tested on more than 10,000 women .
He also believes that such home systems may be available in five years, at least in the UK, to improve detection and prevent some women from undergoing unnecessary testing.
Spanish Doctor Manuel Rodriguez-Justo, of University College London, said this is an "exciting study showing that it is possible to detect pre-cervical cancer that has a high risk of becoming invasive cancer. "
And all this, he explained," thanks to urine and vaginal samples collected by women in their own homes and comfort. "
"This has the potential for revolution Tell how a positive pap test is followed, in addition to facilitating testing for women from countries without screening programs."
Sophia Lowes, director of health information at Cancer Research UK, told the BBC that "the results are seeing promising to detect women with advanced cell changes. "
"But we need to know if this test detects all changes and if it succeeds in a larger group of people."  Robert Music, executive director of another UK organization specializing in cervical cancer, Jo & # 39; s Cervical Cancer Trust, defined it as a "turning point."
"For those women who find current methods difficult, including those with Physical Disabilities or Trauma, may mean access to screening tests that work in a more acceptable and accessible manner ," he said.
"It can make you s who require treatment more quickly identified and the number of women who would do unnecessary research is reduced."
